HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 600,949, dated March22, 1898..

Application filed June 24, 1897. Serial No. 642,028. (No model.)

To all whom it may concern:

Beitknown that I,NoRMANIsAoHsoN,acti zen of the United States, residingat Marion, in the county of Cassia and State of Idaho, have inventedcertain new4 and useful Improvements in Hay-Carriers, of which thefollowing is a specication, reference being had therein to theaccompanying drawings.

My invention relates to improvements in hay-carriers of that class knownas sheaveframe catch, in which the sheave-frame on reaching the limit ofits upward movement disengages the carrier from a stop on the way andalso operates a retaining device to prevent the sheave-frame fromdescending.

The objects of the invention are to provide a stop which is always inthe right position, even if the cable or way twistsand which can bereadily removed and replaced; to provide an extremely simple form ofcatch-lever for engaging the stop which is adapted to reduce the wear ofthe parts to a minimum andV to insure their more perfect working andalso to provide for the taking up of any wear upon the parts, and,lastly, to provide an extremely simple catch for the sheave-frame whichwhile holding it securely will permit it to swing without danger oftwisting the head of the sheave-frame.

The invention is illustrated in the acconr,

panying drawings, in which- Figure lis a side elevation of the carrierin place upon the way, parts being broken away; and Fig. 2 is an endview, the upper portion of one of the lower rollers 7 being broken off.Figs. 3, 4, 5, 6, and7 are views of modications.

In the drawings, the numeral 3 designates the wire or cable way uponwhich the carrier is designed to run. The way carries a stop 4, having acone-shaped head 2, with the narrow neck in rear providing an annularshoulder 4b, which is adapted to be engaged by the catch-lever of thecarrier to retain the'carrier against movement while'the load is beingele* vated. The stop is made in two parts, as shown, each part beingprovided with a longitudinal groove to receive a portion of the cable orway, so that when the parts are placed together the cable is securelyclamped between them. Suitable means are provided for fastening the twoparts together-such, for instance, as the setscrew 4.

The carrier consists of a double frame 5, substantially rectangular inshape, carrying rollers 6 at its upper side, adapted to run upon thecable, and rollers 7 at is lower corners, over which the hoisting-ropepasses.

The catch-lever 8 is pivoted between the two parts of the carrier at 8and has a hooked end 9. A roller 9a is provided on this hooked end,which is adapted to rest behind the annular shoulder on the stop, theshoulder being slightly undercut for this purpose. It will thus be seenthat when the catch-lever is operated to release the carrier the rollerrides easilyl off from the shoulder without wear on the parts. A secondroller is pivoted in a recess in this arm to the rear of the hooked end,which is adapted to ride upon the incline face of the stop and thusrelieve the lever from contact with said stop. The forward end ofthelever passes across the slotted portion 5L of the carrier-frame, intowhich the T-shaped head 10' of the sheaveframe rises at the limit of theupward movement of the load, so that this T-shaped head lifts the end ofthe catchlever to release the carrier from the stop. The continualcontact of the sheave-frame with the end of the lever is apt to wear theparts, so that in time the lever would not be lifted far enough todisengage it from the stop. To proat 13, consisting of two plates 13a13b, each` having a hooked lower end adapted to engage one of the armsof the Tshaped head of the sheave. These plates are connected so thatthey turn together and are provided with portions overhanging the hookedportions, against which the head strikes as it approaches, so that theplate is rocked to draw the hooks up under the head l0. Thespringpressed arm 14 bears against the upper side of theretaining-plates and drops over a shoulder l5 when the head is in placewithin the recesses, so that it is held securely against downwardmovement. This arm is prefer IOO ably narrower than the space betweenthe plates of the retaining device and is provided with a transversepivot carrying antifrictionrollers 14:, which engage the shoulders ofthe retaining device. The sheave-frame is also of less thickness thanthe retaining device, so that when the head is held thereby the upperportion of the sheave-frame can swing freely back and forth toaccommodate itself to the swinging of the load or when the load dragsupon the top of a stack which has been piled up nearly to the table, sothat there is no danger of bending or breaking the head.

I prefer to connect the two plates of the retaining device so that theywill move simultaneously by forming the pivot pin with squared portionsengaging correspondingly square openings in the plates.

As shown in Fig. 3, I may employ a modified form of sheave andsheave-frame which is provided with a clutch for positively locking thedraft-rope when the frame is engaged and supported by the carrier. Theframe h herein shown carries three sheaves d, d', and d2 and is providedwith a hook, to which one end of the hay-sling is attached. The otherend of the sling is attached to a second frame carrying twoV sheaves,over which the draftrope passes, as shown.

The T-shaped head d has a shank having its lower end bifurcated to formarms e, which are pivotally connected to the outside frame at a pointbetween the sheaves a d'. A jaw g, having a curved face, projects upfrom between the arms e at the junction of the same with the shank ofthe head, and when the head is held by the carrier the weight of theload will press said jaw into engagement with the draft-rope, passingover the sheave a and positively clamp the same. By using the threesheaves and threading the rope, as shown in Fig. 3, both of the pulleyswill be elevated evenly and thus prevent the load from turning upedgewise, so that when it is tripped it will spread out evenly over thestack. The weight of the load will also regulate the compression of thesame. Thus by using a short sling and a long slack rope the bundle willbe compressed as long as the weight thereof will effect it.

In order to move the load laterally or longitudinally in relation to thecarrier without twisting the ropes, I have modified the construction ofthe carrier, as shown in Figs. 4: and 6, in which the pulley m isarranged at right angles to the carrier, being journaled in bracketsdepending from and supported by the bolts upon which the upper rollersare journaled. Upon the opposite side of the carrier and pivotallysupported in similar brackets is a sheave-frame y, in which the sheave nis mounted. The trunnions of this frame are placed slightly above thecentral line thereof, as shown in the detail View, to effect an easieroperation of the same. The sheave-frame has in this form the T-headarranged parallel with the sides thereof, and

thus the sheaves are arranged transversely in relation to the carrier.

Having thus described my invention, what I claim isl.v In combinationthe way, the stop having an undercut flange, the carrier and thecatchlever havin g a roller adapted to rest against `said undercutiiange, substantially as described.
